It has been decided. I’ll have a personal observatory!
Now the first problem is were it will be. Ideally it shoud be near you, at a high altitude and far from any light! Moreover it shoud be in a laminar area with prevailing night winds.
Now what is near for me could easely be far for you or the reverse. Since you have to expect a lot of trips to your construction site near for me was something around half an our of driving.
So I looked at the light pollution map (lightpollutionmap.info) ad identify areas half to one hour drive from my home were light pollution was reduced. Then I started to search for some plot for sale in one of those areas. In my negtiboug there are a lot of protected areas. Thus the potential area were higly reduced.
It took for me three years to find a non ideal plot.
